An excellent historical account of Jackson's life and career can be found in Stonewall Jackson: The Man, the Soldier, the Legend (ISBN: 0028646851) written by James I. Robertson, Jr.. Robertson is an Alumni Distinguished Professor of History at Virginia Tech. If you attend Virginia Tech, or are planning on attending, I'd highly recommend his Civil War classes.

For a historical fiction account of Jackson's career during the Civil War, check out Jeff Shaara's Gods and Generals (ISBN: 0345422473). This book relies heavily on Robertson's work as its primary source of information about Jackson. You'll definitely notice this if you read these two works in succession. Gods and Generals gets you inside the head of Jackson, allowing you to imagine the battles of the war as if you were seeing them first hand.
